IMPROVEMENT IN THE MANUFACTURE OF SHOE-N AILS.

Specification forming part of Letters Patent No. 181,619, dated August 29, 1876 application filed July 15, 1876.

To all whom it may concern:

Be it known that I, LLOYD W. AUSTIN, of Taunton, in the county of Bristol and State of Massachusetts, have invented an Improvement in the Manufacture of shoeNails, of

which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure l is a plan of a nail-plate, illustrating the manner in which the blanks are cut therefrom. Fig. 2 is a perspective view (enlarged) of one of the blanks out from the nailplate shown in Fig. 1. Fig. 3 is a perspective View (enlarged) of one of my improved shoenails finished and ready for use.

Shoe-nails having untapered sides and a flat or chisel-shaped clinching-point have heretofore been made only from wire, the pointhaving been formed by milling. This latter operation is, however, tedious, and occasions aconsiderable waste of stock, and nails of this description have not heretofore been cut from a plate, owing to the difficulties experienced in the formation of the point.

My invention has for its object to avoid the waste of stock above referred to; and consists in cutting the blank in a peculiar manner from a nail-plate, so as to leave parallel sides and a point beveled on one side only, this point being afterward changed in form, so that two opposite sides will taper equally, by means of the dies which produce the-corrugations or notches in the shank of the nail.

To enable others skilled in the art to understand and use my invention, 1 will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents a squareedged nail-plate, from which the blanks B, Fig. 2, are out in a suitable nail-machineiu the following manner, the mechanism for feeding the plate being so constructed as to give the required movements thereto: The end of the plate A is first cut on the lines a b c b. A blank is then cut on the line (1 e onone side of the plate, which is afterward fed forward and moved laterally, or turned in such a manner as to cause the cutter to sever the next blank from the opposite side of the plate on the line f g, after which the plate is again fed forward and moved laterally, or turned so as to cause a third blank to be severed on the line It i, and so on until the plate is used up; and it will be seen that by this method each blank is cut with parallel sides and a chiselshaped clinching-point, k, beveled on one side only, as seenin Fig. 2, this form being produced without any waste of stock whatever, except that occasioned by first cutting the plate on the lines a b c b and the usual butt or waste piece at the end of the plate.

Each blank, as it is severed from the plate, is seized and compressed by dies, which are so shaped as to form the head I and the notches or corrugations m, and also to bend the point .so that its two opposite sides It a will be The within-described,im movement in the art of manufacturing shoe-nails, the same consisting in cutting the blank from a nail-plate so as to leave parallel sides and a point beveled on one side only, as shown, and afterward finishing the nail and changing the form of its point by dies, substantially as set forth.

Witness my hand this 6th day of July, A. D. 1876.
